RAIL-JOINT LOCK AND STABILIZER.

Application filed October 17,1325; Serial No. 33,009.

This invention relates to rail joints and stabilizers and has for its object to provide arail joint and stabilizer simple in its construction but efficient in, securely holding the rails in place by means that will not be shaken or jolted apart.

An object of the invention is to securely lock the nuts of the bolts fastening together the side plates by a nutlock easily removable when desired and easily applied to lock the nuts in place.

It is a further object of the invention to provide means for securely holding the rails from either vertical. or lateral displacement the one relative to the other.

With these and other objects in view which will be apparent from the description, we will now describe our invention in connection with the accompanying drawings in which:

Figure 1 is a side view of our invention.

Fig. 2 is a side view of the other side of the invention; and

Fig. 3 is a sectional View of the invention.

Where the rails 1 meet, we provide a chair plate 2 carrying a fish plate 3. These plates may be integral as shown in Fig. 3. The plates 4 and 3 are clamped to the rail 1 by bolts 5 having heads 7 on one end and nuts 9 on the other end.

To prevent the nuts from turning after they have been screwed up as tightly as pos-' sible to hold the plates 3 and L and the rail 1 clamped together as shown in Fig. 3, we provide a notch 10 in one of the plates as 3. The notch may extend from end to end of the plate or only part way as desired, and we insert in the notch a bar 11. The bar is firmly held in the notch 10 and resting against the lower sides of the nuts 9 prevents their turning on the bolts 5.

In case it is desired to remove the plates, all that is necessary is to strike on the end of the bar 11 and remove it from the notch 10 when the nuts 9 on the bolts 5 may be unscrewed and the plates removed.

It will be observed that the chair plate passes over the bottom of the rail around over the lower rail flange and is firmly held by the bolts 5, and since these plates embrace the ends of meeting rails they will, of course prevent any vertical displacement of one rail relative to the other. Furthermore, the plates 3 and 4 held by the bolts will prevent any lateral displacement of the rails and a'car wheel may pass over theends of the rails on as solid a track as in the middle oi the rails and since there is no possi bility of nuts working loose on the bolts, the rail joint or stabilizer will remain as inflexible as other portions of the rail.

YVe may form grooves 13 in the side of the plates to produce a firm clamping effect of the plates on the web of the rail at their tops and bottoms.

It will thus be observed that we have devised a simple but highly elficient device for preventing the movement of the rails relative to each other at their ends as well as preventing the lateral movement of the rails relative to each other and yet which joint or stabilizer may be easily dismantled.

What we claim as new is:

l. A rail joint and stabilizer comprising a combined chair and fish plate adapted to extend under the lower flanges of the meeting rails and also extend up the web of the rails, but terminating short of the top of the web, and having a notch therein, a second plate adapted to embrace the lower flanges of the rails and also to extend up the sides of the meeting rail webs, a plurality of screw-threaded bolts passing thnough both plates and the webs of the rails, nuts for clamping the plates to the webs and a rigid bar with its end insertible in the notch in the side of the plate, said bar resting against a side of the nuts to lock the same.

2. A rail joint and stabilizer comprising a combined chair and fish plate adapted to extend entirely under the bottom flanges of the meeting rails, the fish plate being integral with the chair plate, said fish plate having a. thickened portion and a notch on the exterior of the thickened portion and a channel in its inner side, a plurality of screw-threaded bolts, for clamping the fish plate to the webs of the rails, nuts on the bolts, and a nutlock comprising a rigid bar insertable in either end of said exterior notch with its broadest sides vertical and its narrowest edges resting in the notch on the fish plate and against the sides of the nuts to prevent their turning.

3. A rail joint and stabilizer comprising a chair plate and a fish plate integral with each other and adapted to embrace the lowerfiange-s of the rails and to extend from the flanges to near the top of the webs of the rails, the side of the plate having a channel therein between the plate and rail web,
